The joist line and arrows shown in my clip are a single detail component.
And my tag is a text only version, tagged and moved to suit my joist line/arrow detail component placement.
Without the detail component, I would have to hide all the joists I don't want to see in the view. Hidden elements tends to be unreliable, and alot of extra work itself, so I chose to create a detail component for this purpose instead.
The other thing you could do...is chose one of the joists in the beam system you want visible. Change it's structural usage - to something you won't be needing, possibly like horizontal bracing. Change horizontal bracing linetype to that of a joist. This way you can hide all joists in the view but the "horizontal bracing" joist would remain visible.
